This application claims the benefit and priority of U.S. Provisional Patent Application Ser. No. 61/367,143 filed on Jul. 23, 2010, which is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates to a system and method for construction of a building from components, supplies and tools which are transported to the desired construction site in a shipping container, thereby facilitating quick and efficient building construction, especially in remote areas.

BACKGROUND OF THE INVENTION

The present invention relates to a building system and method for construction and use in locations and environments where it is difficult, if not impossible, to procure adequate building materials and skilled labor. Such locations include, without limitation, areas which have been ravaged by war, storms and other disasters (hereinafter “disaster areas”). In such disaster areas, construction materials, tools and skilled labor are generally unavailable, yet it is precisely in such areas where at least some initial building is desperately needed so that the process of recovery can begin.

The building system and method of the present invention are a significant improvement over existing building systems used in disaster areas. For example, in war-ravaged areas, the standard military building system typically involves three stages or phases for establishing a progressively more substantial presence at the location. Phase 1 consists of a tent on natural dirt as a floor. In phase 2 a wooden floor is built under the existing tent. In phase 3 a wooden shell is built over the tent, resulting in a shelter which is prone to fire, rot, termites, decay and warpage. Such shelters have a limited life expectancy and are uncomfortable to inhabit. This staged process is due in part to the materials used, and the considerable time and effort required, for the above described standard military building.

By contrast, the building of the present invention can be completely erected in a single process within a fraction of the time, and resulting in a much more habitable and permanent building, than is the case with the above described, three-stage, standard military building. The present invention essentially replaces all 3 phases of the standard disaster-area building system with a semi-permanent structure which is fireproof, not subject to decay, insects or warpage, and is much more habitable than said standard system.

The preferred system of the present invention provides for the use of metal framing members, fiber cement wall boards, and metal wall and roof cladding, which are totally noncombustible and are not subject to rot, termites, decay or warpage. This provides significant advantages over traditional military building systems involving the use of wood and other building materials at disaster areas, which are prone to such problems. Moreover, the materials for such traditional military building systems, including plywood and wooden framing systems, are typically imported from North America and drain the eco-system, whereas the materials used in the present invention can be sourced worldwide without loss of timber or associated damage to the eco-system.

As an alternative to such traditional military building systems, the prior art includes so-called relocatable buildings (“RLBs”) which are typically shipped via flat pack containers. An advantage of the RLBs is that they can be shipped in a flat configuration of 4 units. However, there are many disadvantages associated with RLBs, including the following: they are limited in size to 8 feet by 20 feet, which is not the standard size used by the U S military; they are not rigid or semi-permanent; they are fragile to impact and wind; and they have an undesirable flat roof. Moreover, manufacturers of the RLBs are usually located outside the United States, such that the electrical wiring and related electrical components provided with RLBs must be replaced with 110/220v for use by U.S. customers such as the U.S. military. Additionally, a crane or other lifting device is required to help assemble RLBs, and the RLB components are not fireproof.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a building system and related method for rapid deployment via a shipping container to a disaster area where the building can be erected in minimal time with minimal labor. Packed within the shipping container are all of the necessary building components, including modular wall and ceiling panels, roof trusses, roof panels, and wall and roof cladding. Also packed within the shipping container are all of the building materials, tools, fasteners and supplies needed to erect the building. Upon arrival of the container at the disaster area, its contents can be expeditiously unloaded and the building can be constructed with a minimum of effort, time and labor, with minimal need for measuring or cutting of any materials, and without the need for a crane or other lifting device.

In the preferred embodiment of the present invention, the wall and ceiling panels are comprised of standard-sized, full width—full height sheets of cement fiber board, measuring 4 feet by 8 feet (1220 mm×2440 mm), so that there is no cutting or fitting required on site for said panels. By not having any panel waste materials, the net payload to be transported via the container to the disaster area can be kept to the bare minimum, and all the transported panel components can be incorporated into the work. Similarly, there is no cutting, fitting or waste material involved in connection with the roof trusses and roof panels. No waste material means no debris to dispose of, and site erection is eco-friendly. The present invention provides for a structure having the same standard size as existing building systems used by the U.S. military in disaster areas, i.e., 16 feet wide and 32 feet long, with an 8 foot ceiling (4870 mm×9756 mm×2440 mm). To simplify erection in disaster areas where the instant invention may be deployed, and where skilled craftsmen are likely unavailable, the major building components of the invention are preassembled and modularized, requiring no measuring or cutting.

The preassembled and modularized building components of the present invention include wall panels, ceiling panels, roof trusses and roof panels, each of which is light enough to be lifted manually and small enough to be fitted into a 20-foot shipping container. To further simplify erection of the building in accordance with the preferred system and method of the present invention, there are provided 6 identical-sized wall panels, 8 identical ceiling panels, 9 identical roof trusses and 8 identical roof panels.

The preassembled wall and ceiling panels of the present invention preferably have a finished inner surface which is faced with fiber cement wall board. The outer surface of the wall and ceiling panels may be equipped with electrical wiring, plumbing, telecommunication cables and other accessories, and are covered with insulation.

Upon arrival of the shipping container at the desired building site, the wall panels are removed from the container, stood erect at the building site and connected to one another. Ceiling panels that were also shipped in the container are then lifted in place, spanning and supported by the wall panels, thereby creating a building interior envelope within a matter of hours.

Roof trusses and roof panels, also shipped in the container, are then lifted in place, the roof trusses supported by the ceiling panels and the roof panels supported by the roof trusses. The roof panels and wall panels are then faced with pre-cut metal cladding, also shipped in the container, resulting in a walled building under roof in minimal time without the need for any measuring or any cutting, and without the need for any crane or other lifting device. The preferred building of the present invention, containing 512 square feet and having a standard military configuration 16 feet wide and 32 feet long, can be erected in approximately 10 hours by a 6-person team having minimal building skills. This is much less time, involving much fewer people with much less skill, than is required with existing building systems deployed in disaster areas.

The building of the present invention may be erected on and anchored to an existing concrete slab or other existing foundation at the building site. Alternatively, the shipping container of the present invention may include preassembled floor panels having a finished inner surface faced with fiber cement wall boards. The floor panels may be anchored to the ground at the desired building site, and the building may erected on the floor panels. The building may be fastened and secured on all 4 exterior and interior corners with metal “L” brackets which are through-bolted.

In summary, the preferred building system of the present invention provides the following features and benefits:

1. Simple erection of building components, including modular wall panels, ceiling panels, roof trusses and roof panels, facilitating work by soldiers and others who may have minimal construction training and/or experience.

2. Indefinite lifespan of the building.

3. The entire building system, including components, materials and tools, fits into one shipping container.

4. Rapid erection, multi-purpose use of building.

5. Snow, wind and earthquake resistant.

6. Made of all fire-resistant materials.

7. Will not rot, decay or warp, and is not subject to termites or other insects.

8. Building can be extended infinitely in length via additional containers.

9. Interior walls can easily be added.

10. Complete system uses the above structure and adds standing seam sheeting for exterior walls and root cement fire board for interior wall, 1 hour fire rated steel door.

11. Building site is without construction debris and is ecologically friendly.

12. The building can be rapidly erected at the desired site with minimal need for measuring or cutting materials, and without the use of cranes, forklifts or other lifting devices.

13. The building of the present invention has a universal flexibility in that it can be used as housing, offices, medical clinic, classroom, latrines, mess halls and so forth.

DETAILED DESCRIPTION

FIG. 1 generally depicts the finished building 10 of the present invention in its preferred embodiment. FIG. 2 depicts building 10 adjacent to shipping container 12 of the preferred embodiment of the present invention. Container 12 is large enough to accommodate, and is used to transport, all of the building components, supplies and tools needed to construct the finished building 10 at the desired building site.

Container 12 is preferably a 20-foot long metal container which complies with the specifications and standards set by the International Organization for Standardization, commonly referred to as a 20-foot ISO shipping container. Container 12 can be shipped by any number of transportation means, including truck, train, boat, and air transport.

FIGS. 3 and 4 generally depict the building components, supplies and tools loaded and nested inside container 12 in the preferred embodiment of the invention. Container doors 14 are closed during transport of the loaded container 12 to the desired building site. Doors 14 are reopened when the container 12 has reached the desired building location, so that the building components, supplies and tools can be unloaded and the building can be constructed.

The building components preferably include a plurality of preassembled, modular wall panels 20, as best depicted in FIGS. 5, 6 and 7. In the preferred embodiment of the invention, each wall panel 20 is approximately 16 feet long and 8 feet high, more preferably 16′2″ by 8′0″, and fits comfortably inside a 20-foot ISO container 12 as shown in FIGS. 3 and 4.

As depicted in FIG. 7, each wall panel 20 preferably includes 4 full sheets of fiber cement wall board 22, each sheet 22 preferably being 4 feet wide, 8 feet long and 0.236 inches thick. Each wall panel 20 is preferably preassembled, prior to being loaded and shipped in container 12, by affixing 4 adjacent sheets 22 to wall framing members 24, as depicted in FIG. 6. Wall framing members 24 are preferably comprised of metal studs having a channel-shaped profile, said studs preferably having the following dimensions: metal thickness of 0.75 mm; stud width of 1.61 inches (41 mm); and stud depth of 3.50 inches (89 mm)

In the preferred embodiment of the invention, each sheet of wall board 22 is attached to framing members 24 by using clips 100, commonly referred to as “omega clips.” Omega clips 100 have a profile somewhat similar to the Greek capital letter omega, said profile providing a channel which accommodates the insertion therein of an edge portion of sheet 22. Also known sometimes as “hat omega” clips because their profile resembles that of a top hat, omega clips 100 may be obtained through material suppliers such as BAATCO (Burj Al Aaj Building Materials) located in Dubai. The clip profile includes a flange which extends parallel to sheet 22. The flange can be provided with holes to accommodate screws passing therethrough, said screws being used to attach the omega clips 100 to their supporting frame members 24. As shown in FIG. 7, omega clips 100 are preferably used along the perimeter edges of sheets 22 which abut other sheets 22, but not along the perimeter edges which form an angle with other surfaces such as the floor, the ceiling or an intersecting wall.

As preassembled, each wall panel 20 has a finished inner surface 26 and an outer surface 28, as best depicted in FIGS. 7 and 6. Wall framing members 24 are preferably provided with openings 23 along their lengths, as depicted in FIG. 5, to accommodate the passage therethrough of electrical wiring, plumbing, telecommunication cables and other conduits that may be run along the outer surface 28 of the wall panel 20.

The outer surface 28 of preassembled wall panel 20 is preferably covered with wall insulation 30, as shown in FIG. 6. A preassembled wall panel 20 may also be provided with one or more openings through one or more sheets 22 of wall board, suitable to accommodate building accessories such as air conditioners, windows, doors and electrical outlets. For example, as best depicted in FIGS. 5-7, a wall panel 20 may have an opening 27 to accommodate an air conditioner, an opening 29 to accommodate a door, and openings 25 to accommodate electrical outlets.

Each preassembled wall panel 20 preferably has a total weight of approximately 300 pounds, sufficiently light to be carried by 6 workers without the need for using a crane or other lifting device, as such devices are generally unavailable in remote locations where the present invention may be deployed.

In the preferred embodiment of the invention, the loaded container 12 includes a total of 6 wall panels 20 which are used to form the walls of building 10, as shown in FIG. 5, as follows: one 16-foot long wall panel is used for the front wall 32 of the building; another 16-foot long wall panel is used for the rear wall 34 of the building; two other 16-foot long wall panels, placed side-by-side, are used for the left side wall 36 of the building; and two other 16-foot long wall panels, placed side-by-side, are used for the right side wall 38 of the building. As so configured in the preferred embodiment of the invention, building 10 has a rectangular footprint measuring 16 feet wide and 32 feet long, which is the standard size and configuration favored by the U.S. military, and can be used for buildings such as barracks, offices, latrines, and mess halls.

It is understood that building 10 of the present invention is not limited to a 16-foot by 32-foot rectangular configuration. For example, each of the front, rear and side walls of building 10 may include any number of wall panels 20, placed side-by-side so as to form a building having a desired width and length.

When the loaded container 12 arrives at the desired building site, the preassembled wall panels 20 may be unloaded from the container by soldiers or other workers, who carry the wall panels to the site where the building is to be erected. The bottom of each wall panel is placed on top of and is supported by a suitable foundation for the building, for example an existing concrete slab. Alternatively, as described in further detail later below, the wall panels 20 may be placed on and supported by preassembled modular floor panels 110, depicted in FIG. 21, which may be shipped in and with container 12.

FIG. 5 depicts a typical wall erection for the preferred building in accordance with the present invention. Wall panels 20 are erected by standing them up straight, with each of the inner surfaces 26 facing and forming the building interior. As shown in FIG. 5, rear wall 34 and right side wall 38 have already been stood upright. To keep them standing upright during the construction process, rear wall 34 and right side wall 38 are preferably fastened together along their adjoining edges by the use of suitable fastening means such as screws, which are sometimes referred to in the industry as “grabber” screws (hereinafter “screws”). Such fastening means are among the building components transported in container 12 of the present invention.

FIG. 5 also shows the left side wall 36 in the process of being stood up erect by workers. After the left side wall 36 is stood erect, the adjoining edges of the left side wall 36 and the rear wall 34 may be fastened together with suitable fastening means such as screws.

The front wall 32, shown in FIG. 5 in the supine position, is similarly stood up like the other walls. The adjoining edges of the erect front wall 32 and the erect side walls 36 and 38 may be fastened together with suitable fastening means such as screws, similar to the manner in which the adjoining edges of the rear wall 34 and the side walls 36 and 38 may be fastened together.

The perimeter of the building is established once all the wall panels shown in FIG. 5 have been stood erect. This can be accomplished in the preferred embodiment of the present invention in approximately 2 hours by 6 workers, without the need for any measuring or cutting of any materials, and without the need for any crane or other lifting device. If desired, interior wall panels may be loaded and shipped with container 12 to the building site, where they may be installed within the building interior to create interior spaces of various sizes and shapes. For example, an interior wall panel 8 feet high and 16 feet in length, with both sides finished with fiber cement wall board and with an opening to accommodate an inner door, may be used in the middle of the building to create 2 interior offices within the building, each office measuring 16 feet by 16 feet.

The building components of the preferred embodiment of the invention also include a plurality of preassembled, modular ceiling panels 40, as best depicted in FIGS. 9, 10, 18 and 19, for use in constructing a ceiling for building 10. In the preferred embodiment of the invention, each ceiling panel 40 measures approximately 16.75 feet long and 4 feet wide, more preferably 16′9.26″ by 4′0.55″, and fits comfortably inside a 20-foot ISO container 12 as shown in FIG. 4.

As best depicted in FIG. 9, each ceiling panel 40 preferably includes 2 full sheets of fiber cement wall board 42, each sheet 42 preferably being 4 feet wide, 8 feet long and 0.236 inches thick. Each ceiling panel 40 is preferably preassembled, prior to being loaded and shipped in container 12, by affixing 2 adjacent sheets 42 to ceiling framing members 44, depicted in FIG. 18. Ceiling framing members 44 are preferably comprised of metal studs having a channel-shaped profile, said studs preferably having the following dimensions: metal thickness of 0.75 mm; stud width of 1.61 inches (41 mm); and stud depth of 3.50 inches (89 mm)

In the preferred embodiment of the invention, each sheet of wall board 42 is attached to framing members 44 by use of omega clips 100, similar to the way that each sheet of wall board 22 is attached to framing members 22 as described above. Omega clips 100 are preferably used along the perimeter edges of sheets 42 which abut other sheets 42, but not along the perimeter edges which form an angle with other surfaces such as an intersecting wall.

As preassembled, each ceiling panel 40 has a finished inner surface 46 and an outer surface 48. Ceiling framing members 44 may be provided with openings along their lengths to accommodate the passage therethrough of electrical wiring, plumbing, telecommunication cables and other conduits that may be run along the outer surface 48 of ceiling panel 40. The outer surface 48 of preassembled ceiling panel 40 is preferably covered with ceiling insulation 50, as depicted in FIG. 11.

A preassembled ceiling panel 40 may also be provided with one or more openings through one or more sheets 42 of wall board, suitable to accommodate building accessories such as light fixtures and electrical outlets. Each preassembled ceiling panel 40 preferably has a total weight of approximately 165 pounds, sufficiently light to be carried by 4 workers without the need for using a crane or other lifting device, as such devices are generally unavailable in remote locations where the present invention may be deployed.

In the preferred embodiment of the invention, the loaded container 12 includes a total of 8 ceiling panels 40, each ceiling panel 40 measuring 4 feet wide by 16 feet long, which are used to form the ceiling of building 10 having a rectangular footprint measuring 16 feet wide and 32 feet long.

It is understood that building 10 of the present invention is not necessarily limited to a 16 foot wide by 32 foot long rectangular configuration. Accordingly, if building 10 for example has a width of 20 feet rather than 16 feet wide, the ceiling panels 40 will each have a corresponding length of at least approximately 20 feet, sufficient to span the distance between and rest upon the side walls 36 and 38 of the building.

The preassembled ceiling panels 40 may be unloaded from container 12 at the building site by soldiers or other workers who carry the ceiling panels 40 from container 12 to the building site. After the building walls have been erected, the ceiling panels 40 are then lifted in place by the workers, such that in the constructed building each ceiling panel 40 spans the distance between and is supported by the side walls 36 and 38, as depicted in FIGS. 9 and 10, with the finished inner surface 46 of each ceiling panel 40 facing downward and toward the inside of the building. In the preferred embodiment of the invention, wherein building 10 has a rectangular footprint measuring 16 feet wide and 32 feet long, 8 ceiling panels 40 placed side-by-side span the 32 foot distance between the front and rear walls 32 and 34 of the building.

Adjacent ceiling panels 40 are preferably fastened together along their adjoining edges by the use of suitable fastening means such as screws. The ceiling panels 40 are also preferably fastened to the side walls 36 and 38 and (for the ceiling panels adjacent to the front and rear walls) to the front and rear walls 32 and 34 by suitable fastening means such as screws. The fastening means for ceiling panels 40 are among the building components loaded and transported in container 12 of the present invention.

The 8 ceiling panels 40 in the preferred embodiment of the invention can be installed, i.e., placed and fastened in their proper position in the building as constructed, in approximately 1 hour by 6 workers without the need for any measuring or cutting of any materials, and without the need for any crane or other lifting device. The building components of the preferred embodiment of the invention also include a plurality of preassembled, modular roof trusses 60. Each roof truss 60 is triangular shaped in the preferred embodiment, having 2 ends 61 and an apex 63, as shown in FIGS. 11 and 12.

In the preferred embodiment of the invention, as depicted in FIG. 12, each roof truss 60 measures approximately 16.5 feet long, more preferably 16′9.26″, from one end to the other, and is approximately 2.25 feet high, more preferably 28.71″, and fits comfortably loaded inside a 20-foot ISO container 12, nested on top of the ceiling panels 40 as shown in FIGS. 3 and 4.

Each roof truss 60 is preferably preassembled, prior to being loaded and shipped in container 12, and is comprised a plurality of roof truss framing members 64. Roof truss framing members 64 are preferably comprised of metal studs having a channel-shaped profile, said studs preferably having the following dimensions: metal thickness of 0.75 mm; stud width of 1.61inches (41 mm);

and stud depth of 3.50 inches (89 mm)

Each preassembled roof truss 60 preferably has a total weight of approximately 42 pounds, sufficiently light to be carried by 2 workers without the need for using a crane or other lifting device, as such devices are generally unavailable in remote locations where the present invention may be deployed.

In the preferred embodiment of the invention, the loaded container 12 includes a total of 9 roof trusses 60. Roof trusses 60 may be unloaded from container 12 at the desired building site by soldiers or other workers who carry the roof trusses 60 from container 12 to the building site. After the building walls and ceiling panels have been erected, the roof trusses 60 are then lifted in place by the workers, such that the trusses rest upon and are supported by the ceiling panels 40, as shown in FIGS. 10 and 11.

When used in erecting the preferred building of the present invention, the roof trusses 60 are spaced 4 feet apart from each other so as to span the 32 foot distance between the front wall 32 and the rear wall 34 of building 10.

It is understood that building 10 of the present invention is not necessarily limited to a 16 foot wide by 32 foot long rectangular configuration. Accordingly, if building 10 for example has a width of 20 feet rather than 16 feet, the roof trusses 60 will have a corresponding length of 20 feet, sufficient to span the distance between side walls 36 and 38 of the building.

Similarly, it is understood that the building of the present invention is not limited to the preferred roof pitch shown in FIG. 17, which is approximately 1-rise-to-3.5-run, more preferably 14°. The desired roof pitch may be attained by providing each roof truss 60 with an apex 63 extending a desired distance above roof truss horizontal framing member 64 h.

Roof trusses 60 are preferably fastened to supporting ceiling and wall panels by use of suitable fastening means such as screws, which are among the building components loaded and transported in container 12 of the present invention.

The 9 roof trusses 60 in the preferred embodiment of the invention can be installed, i.e., placed and fastened in their proper position in the building as constructed, in approximately 1 hour by 4 workers without the need for any measuring or cutting of any materials, and without the need for any crane or other lifting device.

The building components of the preferred embodiment of the invention also include a plurality of preassembled, modular roof panels 70, as depicted in FIGS. 13, 14 and 15. In the preferred embodiment of the invention, each roof panel 70 is approximately 8 feet wide and 9½ feet long, more preferably 8′1.16″ by 9′7.23″, and fits comfortably inside a 20-foot ISO container 12 as shown in FIGS. 3 and 4.

Each roof panel 70 is preferably preassembled prior to being loaded and shipped in container 12, and is comprised of a plurality of roof panel framing members 74. Roof panel framing members 74 are preferably comprised of metal studs having a channel-shaped profile, said studs preferably having the following dimensions: metal thickness of 0.75 mm; stud width of 1.61 inches (41 mm); and stud depth of 3.50 inches (89 mm)

Each preassembled roof panel 70 preferably has a total weight of approximately 68 pounds, sufficiently light to be carried by 2 workers without the need for using a crane or other lifting device, as such devices are generally unavailable in remote locations where the present invention may be deployed.

In the preferred embodiment of the invention, the loaded container 12 includes a total of 8 roof panels 70. Roof panels 70 may be unloaded from container 12 at the desired building site by soldiers or other workers who carry roof panels 70 from container 12 to the building site. After the wall panels 20, ceiling panels 40 and roof trusses 60 have been erected, the roof panels 70 are then lifted in place by the workers, such that the roof panels 70 rest upon and are supported by roof trusses 60. When used in erecting the preferred building of the present invention, each roof panel 70 rests upon and is supported by 3 roof trusses 60, as shown in FIGS. 13 and 15.

In the preferred embodiment of the invention, wherein building 10 has a rectangular footprint measuring 16 feet wide by 32 feet long, with a roof pitch of 14° as shown in FIG. 17, each roofing panel 70 is 8 feet and 1.16 inches wide, and 9 feet and 7.23 inches long.

It is understood that building 10 of the present invention is not necessarily limited to a 16 foot wide by 32 foot long rectangular configuration having the roof pitch shown in FIG. 17. Accordingly, if building 10 for example has a width other than 16 feet and/or a roof pitch other than as shown in FIG. 17, each of the roof panels 70 will have a corresponding length sufficient to extend from at least the apex 63 to an end 61 of a supporting roof truss 60.

Each roof panel 70 is preferably fastened to supporting roof trusses 60 by use of suitable fastening means such as screws, which are among the building components loaded and transported in container 12 of the present invention.

The 8 roof panels 70 in the preferred embodiment of the invention can be installed, i.e., placed and fastened in their proper position in the building as constructed, in approximately 0.50 hours by 4 workers without the need for any measuring or cutting of any materials, and without the need for any crane or other lifting device.

In the preferred embodiment of the invention, the preferred preassembly of metal studs used as framing member 24, 44, 64 and 74 and 114 includes the use of a profile-forming machine from the Frame Master Company of Auckland, New Zealand. A roll of flat metal stock material, preferably high tensile steel, is passed through the machine, said flat metal stock having a preferred width of 181 mm and a preferred thickness of 0.75 mm. The machine has a series of rollers and punches that form the flat metal stock passing therethrough into a framing member having a “c” or channel profile that is preferably 89 mm wide and 41 mm deep, with a 5 mm wide lip formed on the inside to each side of the channel. The machine also punches out holes in the framing members being formed, said holes accommodating screw connectors which can be passed therethrough to facilitate attachment of the framing members to each other and to other components of the building as it is being erected.

The machine is also used to punch holes, preferably 25 mm in size, out of the central 89 mm section of the stud, in appropriate locations to accommodate the passage therethrough of electrical wires, telecommunication cables and the like, as for example openings 23 as shown in FIG. 5.

The building components of the preferred embodiment of the invention further include roof cladding 80 and wall cladding 90 which are used, respectively, to face the roof and walls of building 10. In the preferred embodiment of the invention, the roof cladding 80 and wall cladding 90 are shipped in container 12 as pre-cut sheets, which can be off-loaded at the desired building site and rapidly attached to the building. As shown in FIGS. 3 and 4, the roof and wall cladding 80 and 90 is preferably shipped nested in sheets between roof panels 70 and ceiling panels 40.

In the preferred embodiment of the invention, the sheets of roof and wall cladding (sometimes referred to in the industry as “standing seam material”) are preassembled from flat galvanized metal stock prior to being loaded into container 12. The preferred preassembly of the roof and wall cladding includes the use of a profile-forming machine from New Tech Machinery Corp. of Denver, Colo. A roll of flat metal stock material is passed through the machine, which forms a “profile” running the length of the stock material, as for example the v-shaped profile 140 depicted in FIG. 20. The profile gives the material desired rigidity against bending, and the material is cut into desired sheet lengths. In addition, the profile-forming machine forms interlocking seams along both edges of the stock material, running along its length. Said interlocking seams provide a means for clipping or fastening together adjoining sheets of cladding.

As shown in FIG. 15, sheets of roof cladding 82 are placed on top of roof panels 70. In the preferred embodiment of the invention, where building 10 has a footprint measuring 16 feet wide and 32 feet long, with a roof pitch of approximately 1-rise-to-3.5-run, more preferably 14°, each sheet 82 of roof cladding 80 is preferably 500 mm wide and is 9′8″ feet long, and the loaded container 12 includes a total of 40 sheets 82 of roof cladding 80.

It is understood that building 10 of the present invention is not necessarily limited to a 16 foot wide by 32 foot long rectangular configuration having the roof pitch shown in FIG. 17. Accordingly, if building 10 for example has a width other than 16 feet and/or a roof pitch other than as shown in FIG. 17, each sheet 82 of roof cladding 80 will have a corresponding length sufficient to extend from at least the roof apex to an end of a supporting roof panel 70.

Adjacent sheets 82 of roof cladding 80 are preferably fastened together along their adjoining edges by the use of suitable fastening means such as interlocking seams running longitudinally along the edges of the sheets 82. The roof cladding is fastened to the roof panels 70 of building 10 by suitable fastening means such as screws.

In the alternative, the floor panels 110 may be loaded and shipped in container 12 without first attaching sheets 112 to floor framing members 114. This alternative may be especially desirable due to weight lifting considerations, as each sheet 112 weighs approximately 154 pounds. In said alternative, when the container arrives at the desired building site and is unloaded, the preassembled floor framing members 114 may be carried to and placed into a desired position at the building site, and then sheets 112 may be fastened to them as described above.

As preassembled, each floor panel 110 has a finished inner surface 116 and an outer surface 118. The finished inner surface 116 may be covered with vinyl, linoleum or some other suitable flooring material glued or otherwise attached to the fiber cement wall board. The outer surface 118 of preassembled floor panel 110 is preferably covered with floor insulation 120.

Each preassembled floor panel 110, with two adjacent sheets 112 fixed in place, has a total weight of approximately 373 pounds, sufficiently light to be carried by 6 workers without the need for using a crane or other lifting device, as such devices are generally unavailable in remote locations where the present invention may be deployed. If an embodiment is desired with lighter carrying components for floor panels 110, then the floor panel may be shipped and erected in accordance with the alternative described above, where each sheet 112 weighs approximately 154 pounds and can be carried by 4 workers, and the preassembled floor framing members of each floor panel 110 have a total weight of approximately 65 pounds and can be carried by 2 workers.
